Skin Cancer: An Overview and More

The second most common type of non-melanoma skin cancer, squamous cell carcinoma, occurs in keratinocytes, the cells in the thickest layer of the epidermis . It is caused by UV-B rays penetrating and damaging the skin, often exposed to unprotected sunlight, most often the scalp, lip, back of the hand, and the top of the ear. While it is treatable, prevention is especially important.
